Profile bio
About Marcin Darnowski
I enjoy working with people and numbers. A job where the insights derived aid in making informed business decisions and generate a competitive edge for the company.I have achieved remarkable success by increasing the margin on wholesale telecommunication services from 5% to 80% through in-depth analysis of billing record. By analyzing telecommunications data, I uncovered unusual behaviors that helped detect fraud. I applied an unconventional approach at Orientelco, where I prepared a financial model for a business plan based on Eurostat data in the tourism industry.
